Cape Town: A tough water-saving regime and the generosity of farmers have given South Africa’s main tourist hub welcome respite from a severe drought and helped push back a dreaded “Day Zero“ when Cape Town‘s taps are expected to run dry.

On Tuesday, the city of four million moved its estimate for “Day Zero” to July 9 from June 4 due to a decline in water usage, and after the Groenland farmers association also released 10 billion litres of water from their private reservoirs into the Steenbras storage dam.

South Africa has declared a national disaster over the drought afflicted southern and western regions, including Cape Town, which means the government could spend more money and resources to deal with the crisis.

Cape Town, which attracts about two million visitors each year, wants to become more resilient as the effects of climate change are felt, similar to other dry cities including Melbourne and California.

“We know that while we are going through a challenging time, we are building a world-class green economy that will be a beacon of hope for many places around,” said Tim Harris, chief executive for Wesgro, a regional trade and tourism agency.

According to the South African Weather Service, two of the driest seasons ever recorded for the city since observations started in 1921 happened in the last three years: In 2015 when 549 mm (21 inches) fell and last year – the driest year on record – when annual rainfall totalled 499 mm.

But, faced with severe water restrictions and punitive levies, residents of Cape Town have cut collective consumption by more than half in the last three years, as the city targets a daily consumption rate of no more than 450 million litres.

At the moment, restrictions make it compulsory for residents to use no more than 50 litres per person per day, as city officials look to see out the hot summer months into winter, when Cape Town usually gets rain.

“We must all keep doing absolutely everything in our power to reach the target set by the national department to reduce our urban usage by 45%,” said Ian Neilson, the deputy mayor.
